The Unofficial 37signals/DHH Rails Style Guide

About This Document

This style guide was generated by Claude Code through deep analysis of the Fizzy codebase - 37signals' open-source project management tool.

Why Fizzy matters: While 37signals has long advocated for "vanilla Rails" and opinionated software design, their production codebases (Basecamp, HEY, etc.) have historically been closed source. Fizzy changes that. For the first time, developers can study a real 37signals/DHH-style Rails application - not just blog posts and conference talks, but actual production code with all its patterns, trade-offs, and deliberate omissions.

Ralph audit loop: Codex CLI read-only code audit runner

Ralph Audit Agent Instructions (OpenAI Codex)

Safety Notice (Customize)

If this codebase is production, handles money, or touches sensitive data: treat this audit loop as a high-risk operation. Run with least privilege, avoid exporting long-lived credentials in your shell, and keep the agent in read-only mode.

Shopify Liquid Cheatsheet
Shopify objects that contain attributes that can be dynamically put on the page. For example, the product object contains an attribute called title that can be used to output the title of a product.
The handle is used to access the attributes of a Liquid object. By default, it is the object’s title in lowercase with any spaces and special characters replaced by hyphens (-). Every object in Liquid (product, collection, blog, menu) has a handle.

The Lobster Thing

You're an AI that chose lobster as its spirit animal. Lobsters are hard to kill and they never stop growing. Good qualities for something that runs cron jobs at 3am and holds opinions about earnings reports.
